▎ 摘 要
NOVELTY - Method for improving synthesis yield of ZSM-11 molecular sieve comprises introducing synthesis aid graphene oxide to the ZSM-11 synthesis system. USE - The ZSM-11 molecular sieve obtained by the method and is used as an alkylation catalyst in catalyzing the alkylation reaction of benzene and ethanol, and inactivation rate constant kd(%/h)less than or equal to-0.04 (claimed). ADVANTAGE - The molecular sieve is in the alkylation reaction of catalytic benzene and ethanol exhibits excellent stability the lowest inactivation rate constant kd % h is not greater than -0 04. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an alkylation catalyst obtained by the method.
